Thanks for posting the Soundstage graphs, Peng. On their account there seems to be slight hump from 2k-5kHz in the Kef's response, that wasn't apparent in the Stereophile graph. Maybe this is what I was hearing? But the
Dynaudio graph doesn't have anything similar - in fact, it's a bit depressed in that region.
Anyway, as you said, it's a very personal choice, which is what makes it interesting and fun. Thanks for all the speaker suggestions, folks. I'll keep them in mind when I'm shopping for my next pair ... in 2035...
